the HOB instrumentals aren't og instrumentals...
basically what koch and then eagle did was recompose basic elements of the instrumentals to enhance the overall quality of the live recordings. what has recently leaked out are some of these layer instrumentals, which while cool and all, they're not the real deal. tattoo tears is probably the most obvious of the batch, being that eagle didn't even match the right drumkit.
some contain legit elements, but all have been enhanced one way or another.
